direct-access

I'm trying to set up DirectAccess on a virtual machine so I can demonstrate it's value and then if need be add a physical machine to host it.

I'm hitting a problem because the Direct Access machine (DA01) needs to have 2 public addresses actually configured on the external adapter but there is a Zyxel Zywall USG300 between the VMware ESXi host and the outside world.

I've summarised my setup in this diagram current setup

If I ping from the LAN to 212.x.y.89 I get a response but if I ping from the VM I get destination host unreachable. I used "route add 212.x.y.89 192.c.d.1" and get request timed out. At that point I see outbound traffic allowed on the Zyxel firewall but nothing coming back.

I'm past my understanding of routing and VMWare so am not sure how to tie down where my problem lies (or even if this setup is possible). So any help massively appreciated.

VMWare ESXi, change the default path for a VM

For some reason VMWare ESXi has decided that one of my VMs is on a completely different path to the path it is actually on. So my VM is on /vmfs/volumes/long-guid-here/my-vm-name but when I try to open it I get the message "File < unspecified filename was not found." Which is not really surprising… >>> More

I need to get VMWare Server running inside of a VMWare ESXi virtual machine

Yes, I know running a virtual machine inside of a virtual machine is a bad idea. Yes, I know it will be very slow.

I'm almost embarrassed to ask this, but I'm stuck. I installed VMWare ESXi on a Mac Pro. It's working great! The problem is that you press F12 to eject the disk, and F12 is what you use to shutdown ESX. I can power down, open the case, pull out the CD drive and use a paper clip to force the drawer… >>> More
